[SOLVED] Modify paccache.timer to only keep one version of packages

Hi

I'd like to modify paccache.timer so as to only keep one version on packages in the cache instead of 3. (default)
I tried :

$ sudo nano /usr/lib/systemd/system/paccache.service
------------------------------------------------
ExecStart=/usr/bin/paccache -rk1

but this gets reverted after a while to the default paccache -r command

Any idea how I can make this permanent ?

Hi

Thanks very much, exactly what I was looking for !

for anyone looking for a quick answer to the same question :

$ sudo systemctl edit paccache.service 

and add

[Service]
ExecStart=
ExecStart=/usr/bin/paccache -rk1

Have good day !

Re: [SOLVED] Modify paccache.timer to only keep one version of packages

Hi

Digging up this old question of mine, I'm trying to modify the service again so that it also cleans the cache from uninstalled packages (# paccache -ruk0)

I can't get this to work, I've tried

[Service]
ExecStart=
ExecStart=/usr/bin/paccache -rk1 && /usr/bin/paccache -ruk0

which throws no error, but doesn't run the second command, and

[Service]
ExecStart=
ExecStart=/usr/bin/paccache -rk1
ExecStart=/usr/bin/paccache -ruk0

which throws an error..

do I need to make a script with those two commands first, and link to that ? seems like there should be a nicer way to do it

Thanks for your help and happy new year !

Re: [SOLVED] Modify paccache.timer to only keep one version of packages

Systemd service files are not shell scripts nor interpreted by a shell, so && would not work.  Instead:

COMMAND LINES
       This section describes command line parsing and variable and specifier substitutions for ExecStart=, ExecStartPre=, ExecStartPost=, ExecReload=, ExecStop=, and ExecStopPost= options.

       Multiple command lines may be concatenated in a single directive by separating them with semicolons (these semicolons must be passed as separate words).
