needs to depend on tcl (not just tcl8.6)

[cmeerw]

* Impact

the usb-modeswitch dispatcher script fails to start on the default installation because it uses tclsh unversioned while we depends on tcl8.6

* Test Case

$ /usr/sbin/usb_modeswitch_dispatcher

shouldn't bail out on an interpreter error

(or better, test that plugging an usb modem is correctly handled)

* Regression potential

The script was bailing out due to a missing intepreter before so the code wasn't tested, it's possible that it triggers errors or could interact with the system in some way. The dispatcher reacts to udev events when an usb modem is connected, so try to use one of those and make sure that there is no negative effect (and if possible that the modem gets correctly handled)

--------------------------

the package currently depends on tcl8.6, but /usr/sbin/usb_modeswitch_dispatcher actually requires /usr/bin/tclsh which isn't provided by tcl8.6, so it likely would need to depend on something like tcl (= 8.6)

Thank you for your bug report

[Josua Dietze (digidietze)]

ALL distributions that I'm familiar with are adding a symlink "/usr/bin/tclsh" to whatever specific version of the shell is included when tcl is installed.

Update: just checked, and the symlink "tclsh" is included with the current tcl package of Debian Sid as well as with the package of Debian Stretch.

@cmeerw, can you try to re-install the tcl package?

[cmeerw (cmeerw)]

@digidietze you might have misunderstood the report.

It's all working fine if the tcl package is installed, as that package includes the /usr/bin/tclsh symlink. But the usb-modeswitch package does not depend on the tcl package, it only depends on the tcl8.6 package (which doesn't contain a /usr/bin/tclsh symlink).

Hello cmeerw, or anyone else affected,

Accepted usb-modeswitch into groovy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/usb-modeswitch/2.6.1-1ubuntu2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-groovy to verification-done-groovy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-groovy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

tested by uninstalling "tcl" and then installing "usb-modeswitch 2.6.1-1ubuntu2".

usb-modeswitch is working fine now with just "tcl8.6" installed (which is listed as a dependency of usb-modeswitch), but no "tcl" package.

See LP: #1903331 for a possible regression.

[Sebastien Bacher (seb128)]

Thanks for pointing that out Brian, it seems not likely to be a regression but just incorrect tagging, the user reported problems on discourse before the SRU was uploaded but we will check to make sure to do no error

[Łukasz Zemczak (sil2100)]

By looking at the comments (and comment #20 especially) it looks like this is not caused by this upload. Releasing.
